Biometric apparatus

Abstract

The invention provides a biometric apparatus having a display which allows a measured person to recognize biometric data easily and reliably irrespective of whether the measured person is on a platform or not. The biometric apparatus for measuring biometric data of the measured person includes the platform on which the measured person gets on, a sensor unit for acquiring the biometric data of the measured person; a display for displaying the biometric data acquired by the sensor unit; and a control unit for determining whether the measured person is on the platform or not on the basis of a signal from the sensor unit and changes the display mode to display the biometric data on the display according to the determination thereof.

       4. The biometric apparatus according to  claim 1 , wherein the body composition data to be displayed on the display includes at least one of the weight, the degree of fatness, the percent body fat, the amount of subcutaneous fat, the amount of offal fat and the body age. 
     
     
       5. The biometric apparatus according to  claim 1 , wherein the display is a full dot liquid crystal display. 
     
     
       6. The biometric apparatus according to  claim 1 , wherein the sensor unit is a weight sensor provided on the platform for measuring the weight of the measured person. 
     
     
       7. The biometric apparatus according to  claim 1 , wherein the sensor unit includes electrodes provided on the platform so as to come into contact with the bottom of the feet of the measured person for measuring a bioimpedance of the measured person. 
     
     
       8. The biometric apparatus according to  claim 1 , wherein the display is fixedly provided on the platform. 
     
     
       9. The biometric apparatus according to  claim 1 , wherein the display is removably mounted to the platform. 
     
     
       10. The biometric apparatus according to  claim 1 , wherein past body composition data measured prior to measuring the body composition data are displayed on the display when the control unit determines that the measured person is not on the platform. 
     
     
       11. A biometric apparatus for measuring body composition data of a measured person comprising:
 a platform on which the measured person gets on; 
 a sensor unit for acquiring the body composition data of the measured person and outputting a signal indicating a status of whether the measured person is on or off the platform; 
 a display for displaying the body composition data acquired by the sensor unit; and 
 a control unit for determining, after having acquired the body composition data of the measured person, whether or not the measured person is still on the platform on the basis of the signal from the sensor unit, and displaying the acquired body composition data on the display in one of different manners according to the determination thereof, wherein: 
 when the control unit determines that the measured person is still on the platform, the control unit causes the display to display the acquired body composition data in one of the different manners based on the signal received from the sensor unit, and, 
 when the control unit determines that the measured person is not on the platform, the control unit causes the display to display the acquired body composition data in another one of the different manners based on the signal received from the sensor unit, 
 the body composition data includes a plurality of types of body composition data, 
 wherein in the one of the different manners a number of types of body composition data displayed on the display is smaller than a number of types of body composition data displayed on the display in the another one of the different manners, and 
 wherein the control unit switches between the different manners in response to the signal indicating that said status has changed. 
 
     
     
       12. The biometric apparatus according to  claim 11 , wherein the body composition data to be displayed on the display includes at least one of the weight, the degree of fatness, the percent body fat, the amount of subcutaneous fat, the amount of offal fat and the body age.
